Application filed February 17,1909. Serial No. 478,425.

To all whom it may concern:

Be it known that I, JOHN H. SHELLEY, a citizen of the United States, and resident of New York, in the county and State of New York, have invented certain new and useful Improvements in Chain-Manipulating Tools, of which the following is a specificatlon.

My invention relates to chain manipulating tools and its novelty consists in the construction and adaptation of the parts, as will be more fully hereinafter pointed out.

In the drawings, Figure 1 is a side view of the tool assembled, a portion of each handle being omitted; Fig, 2 is a perspective of the same parts disassembled;- Fig. 3 is a section is a perspective of the assembled jaws illustrating their use as a link opening tool, and Fig. 5 is a side elevation of the same parts showing their use as a link-closing tool.

In the drawings, 1 is one handle of the other handle provided with an aperture 3 to laterally at 5 to form a wedge shaped jaw 6 terminating in a beveled edge 7 andprovided with a shallow depression 8 on its in-' ner side. A shoulder 9, cooperating in the usual manner with a similar shoulder on the other handle, serves to limit the extent of movement of the handles with respect to each other.

10 is the second handle of the tool curved at 11 where it is jointed to the handle 1, provided with an aperture 12 to receive the connecting rivet 4 and expanded laterally at 13 to form a shoulder adapted to coiiperate with the shoulder 9 of the handle 1. It is then continued in the'same direction at 15 and turned at substantially a right angle and gradually restricted to form a thick wedge shaped jaw 16 havin a slightly concaved surface-17 near its em? and terminating in a chisel edge 18. A hammer head 19 is secured to or made integral with this jaw, being placed on its outer side.

The pur ose for which the tool is designed mainly to e used is to open and close the chains used to encircle the elastic tires of automobiles. Its use as a chain-opening tool is illustrated in Fi 4. Such a chain indicated at 20 is provi ed with one or more longthis link is so placed its free ends 22 are in a line substantially perpendicular with the inner surface of the jaw 6 and the parts are so arranged that the extremity 18 of the jaw 16 if introduced between such free ends 22 and the main body of the link 21 and the jaws are brought toward'each other by pressing the handles 1 and 10 together, then the wedge of the jaw 16 will force the ends 22 away from the main body 21 of the link, so that the links of the chain can readily be removed therefrom. Its use as a chain-closing device is illustrated in Fig. 5. In this case the flat main portion of the link 21 is placed against the inner surface 8 of the jaw 6, another link of the chain 20 is placed between the body of the link 21 and its free open ends 22 and now when the jaws 6 and 16 are brought together by pressing the handles, the movement of the jaw being substantially at right angles to the surface of the jaw 6, the free ends 22 of the link 21 are pressed inwardly to the position shown in dotted line in Fig. 5 (and in full line in Fig. 4) and the chain is effectively closed.

The jaw 6 is provided with a beveled edge in order that it may be used as a screwdriver or chisel and thus avoid the necessity of carrying either of such tools. The jaw 16 is provided with the hammer head 17 in order to avoid the need of carrying a separate-hammer. Both of these combinations have been found useful.

What I claim as new is -1. A chain manipulating tool, comprising pivotally connected handles provided at one end with cooperating jaws, one of said jaws having .a substantially straight inner face with a shallow depression therein adapted to seat the rear wall of the chain links and prevent lateral displacement thereof, the other jaw being disposed at rightangles to said firstmentioned jaw and having a wedge-shaped operating end, substantially as and for the purpose described.
